Despite that omni-directional mobile robots have been employed popularly in several application areas, effort on optimal design of such mobile robots has been few in literature. Thus, this paper investigates the optimal design of omni-directional mobile robots. Particularly, optimal design parameters such as one or double offset distance of wheel mechanism and the wheel radius are identified wi...

We describe a system that employs the use of an omnidirectional camera in tandem with a pan-tilt-zoom (PTZ) camera in order to characterize traffic flows, analyze vehicles, and detect and capture anomalous behaviors. The framework is such that we can generate long-term statistics of traffic patterns while still monitoring unusual activity, even apart from the traffic zone. We use the PTZ in con...

In this paper, we present the method of localization system that uses iGPS (indoor GPS) sensor and Omni-directional vision sensor in the environment involving land mark. The indoor GPS (iGPS) is a simple and cheap localization sensor in the indoor environment. However, the error range of iGPS is too wide to be used in a small size robot. This paper presents a more accurate method of localizatio...

An omni-directional mobility platform design concept using two active split offset castors (ASOC) and one or more conventional castors is presented. An ASOC module consists of two coaxial conventional wheels driven independently and connected to the platform via an offset link. The kinematics and implementation of the omni-directional platform is described and analyzed. Particular attention is ...

This paper presents a CPW-fed compact inverted L shaped microstrip antenna for wireless applications. The proposed antenna provides an omni directional radiation pattern and it utilizes the concept of coplanar wave guide (CPW). The main motive is to simplify the structure and to reduce the overall size of the antenna. This is done by loading the inverted L-strip over the conventional monopole p...

this paper presents a delay compensator fuzzy control for trajectory tracking of omni-directional mobile robots. fuzzy logic control (flc) of the robots is a suitable strategy for dealing with model uncertainties, nonlinearities and disturbances.  on the other hand, in many robotic applications such as mobile robots, delay phenomenon is able to substantially deteriorate the behavior of system's...

Purpose This paper aims to explore how omni-channel data flows should be integrated by specifying what data, agents and information digital technologies (IDTs) considered connected. Design/methodology/approach A multiple case study method is used with 17 British companies. The studies are supported 68 interviews the companies their consumers, 5 site visits, 4 focus group meetings companies’ arc...
